To all whom it may concern:

Be it known. that a citizen of the United States of America, residing inthe city and county of Denver and State of Colorado, have invented a newand useful-Supporting Device for Plastcr- Boards Used in PartitionConstruction, of

-which the following is a specification. This invention relates to.improvements in supporting devices for plaster boards used in partitionand ceiling construction.

The object of the invention is to provide preferably used in connectionwith a channel-bar form of studding and which is so arranged that theplaster boards may thereby be secured to the stud-- dingso that theiradjoining ends will form either a continuous or unbroken vertical joint,or a staggered or broken joint, as may be desired. Further, to provide aclip, comprising an abutment or backing plate and a key-receivingmember, which are so constructedthat when assembled in one way upon thestudding the plaster boards may be secured thereby, so as to formcontinuous adjoining ends, and when assembled in another way upon thestudding, the plaster boards may be so secured thereby as to formstaggered or broken joints. -These objects are accomplished by thedevice illustrated in the accompanying drawings, in which:

Fig. 12 is a perspective View of the abutment plate shownin Fig. 11. Fig. 13 is a horizontal sectional View showing a furthermodification of the clip, ment by which the plaster boards are securedso as to form continuous or unbroken joints; and Fig. 14: is aperspective View of the abutment plate forming a part of this clip.

Referring to the accompanying drawings: the numeral 1 indicates a stud,which is preferably in the form of a metal channel bar, these studs inpractice being arranged at regular intervals and secured at theiropposite ends to the floor and ceiling, respectively.

The plaster boards 2, which are secured to the studding, are a characterof board in common use, such boards being of any required length andwidth and aboutthreeeighths of an inch in thickness. These boards aredesigned to take the place of the usual laths, and in the presentapplication I have illustrated an improved form of clip for securingthese boards to the studding. This 'clip comprises an abutment plate 3,-a cooperating key-receiving member 4, and a key or wedge 5. The plate 3is a rectangularplate of suitable dimensions, which is bent or pressedto form therein a. central longitudinal channel 6, which is U-sh-aped incross-section, and ofslightly greater width than the depth of a stud orchannel bar, while the depth of the said channel is slightly less thanthe thickness of a plaster board. This U-shaped channel 6 is dividedcentrally by a transverse slot 7, which also extends through the plateand is greater length than the width of the channel, so that it extendsinto the plate a suitable disor so that the joints of the alter--showing an arrangethat their a tame on each side of the channel. A slot8 of the same length as the slot 7, is also cut in the bottom of channelintersecting the slot 7, so that the opening through the plate andchannel is cruciform in outline, as will be clearly seen by reference toFig. 7. The key-receiving plate 4 is a U-shaped plate,

' "-bne side of which is equal in length to the width of one of thestuds, while the other side is slightly longer, and is provided with anaperture 9, adjacent to its outer end. T e arrangement of the clip shownby Figs. 1 to 3 inclusive, provides for the attachment of laster boardsin such manner d joining ends form continuous or unbroken-jointsthroughout the length pf the studs, and the arrangement is as follows:The key-receiving U plates 4 are first placed upon the channel bars orstuds, '15

shown by Fig. '2. These plates are made to fit the studs snugly, auditispreferable to press their sides slightly toward eachv other so thatthe.may be sprung upon the studs and thus held by frictional engagement.

The plates 3 are then placed upon the op:

posite sides of thestuds 1, their channels 6 engaging the studsand sidesof the U-plate'; as shown, and{ the longer sides of the U-plateprojecting through the slots 8 in;

the said channels 6. The plaster boards are then placed against theplates 3, with their opposing ends abutting against opposite sides ofthe channel bars or studs 1, and as the channels 6 are of less depththan the thickness 'of the plaster boards, the outer surfaces of thesaid boards will extend slightly beyond the adjacent edges of the studs,as clearly shown by Fig. 2.\ The holes 9 in the projecting sides of theU-plates are so posi- 0 tioned relatively to the thickness of theplaster boards that they are partially covered by the ends of the saidboards, for a reason to be hereinafter explained. The opposing ends ofthe boards thus placed are 5 then clamped to the studs in the followingmanner: Keysor wedges 5, are used for a this purpose, and these wedgesare preferably wire nails of suitable size, which are driven through theholes 9 of the projecting sides of the. U-plates 4 and in engagementboards.

55 ojf the c with the ends of the plaster boards. The holes 9 are ofslightly greater diameter than the nails 5, and as above stated, theyare partially covered by the ends of the plaster The space between thesurface of the plaster boards and the outer margins of these holes isslightly less than the thlckness or diameter ofthe nails, so that whenthe nails aredriven through the said holes, the

50 boards are thereby clamped against the plates 3, the U-plates 4 beingheld stationary by reason of their engagement with the studs.

In Figs. Gto 9 inclusive, the arrangement sired, or they ing holesthrough them,

ips is such that the boards can be secured so that their opposing endswill form continuous or unbroken joints if decan also be secured instagger joint form, as shown by Fig. 9. In this arrangement of the clip,the plates 3 are placed.upon the studs in angles to the positions theyprevious arrangement, or so that the studs pass through the slots 7,which divide the channels 6, and rest against the surface of the plates,as shown most clearly by Figs. 7 and 8. The U-plates'4 are then placedupon the opposite sides of the studs from the plates 3, with their sidesprojecting throu h the dividin slot 7 of the channel 6, the onger ends 0the said U-plates also 'extending positions at right occupy in thethrough and beyond the plate '3. The laster boards are then placedagainstthe p ates 3, their opposing ends being separated only by theprojecting sides of the U-plates, as shown by Figs. 6 and 9, and areclamped to the said centers, as well as at "their ends. The U-' platesonly, are used in securing the boards, at their centers, the plates 3being dispensed with, there beingno need for them, as the boards restdirectly against the studs and are clamped to them.

In Figs. ll and 12 is cation of the clips in which the same style ofU-plate 4 is employed, but in cooperation with an abutment plate 11,.which is a flat plate having a tongue 12, projecting from its centralportion and which is integrall connectedat one end to the plate as sown.

plate and then over substantially parallel with it, so as to form a hookwhich is adapted to engage one side of a channel form of stud, as shown.After the plate 11 has been attached to the stud, the U-plate 4 ishooked This tongue isbent up "at an angle to the upon the opposite sideof the stud, and its lon member passed through, the opening 13 1n theplate, which is made by removing the metal to form the tongue. Theplaster boards are then placed in position with their adjoining endsresting upon the plates 11, and are clamped thereto by the nails 5, inthe manner previously described. This clip provides'for securing theboards with either continuous orstaggered joints, as may be desired.

In 13 and 14, a further modification 105 illustrated a modifiof the asis shown, the clip in this instance being adapted for. the securing ofplaster boards with continuous or unbroken joints only. In thismodification the same style of U-plate 4 is employed as in the otherarrangements, but in connection with an abutment plate 14, having acentral longitudinal channel 15, from the bottom of which is cut atongue. 16, which is integrally connected to the channel at one end,leaving an opening 17 in the bottom of the channel, as

shown.- This tongue 16 engages the side of the stud in the same manneras the tongue 12 in Fig. 11, and a U-plate 4 is hooked over the oppositeside of the stud, its long member extending through the opening 17 Thechannel 15 is of slightly less depth than the thickness of the plasterboards and the plaster boards are placed in position with their endsresting upon the plates and abutting against the sides of the channel15. The key 5 is driven through the aperture in the end of theprojecting member of the 'U- plate, and thereby clamps the ends of theness may be built.

plaster boards to the plates, as in the manner previously described.

In Fig. 10 is shown a U-plate 18, having a key-receiving aperture 19.The extremity of the apertured end of this clip is bent at right anglesto form a rest 20, which is adapted to temporarily support one end of aplaster board when the clip is used in ce'ling construction.
